Market systems are dynamic and changes stimulated by projects are rarely linear, making it difficult to match each activity with a single output and outcome. Rather, activities can generate multiple outputs, and outcomes are interconnected and can occur at different points in the market system. Moreover, traditional M&E approaches tend to emphasize baseline and end line indicators such as volumes and values of production, productivity, income. However, we found that changes in relationships, interactions and behaviors of market actors were much better indicators of sustainable change. Yet these indicators are more challenging to capture.
